These idler arms use powdered-metal gusher bearings with grease grooves to improve performance and service life. This approach allows grease to flow through the bearing to the stud and provides a smooth, durable surface that extends service life.

Moog idler arms also use a double-tapered bearing design that decreases deflection and helps preserve proper toe setting, and they have a larger bearing surface area that distributes the load more evenly.
